Machira asina kurukwa/asina kurukwa, seasiri echinyakare machira, chinhu chakakosha uye chakakosha munzanga yanhasi nekuda kwezvakasiyana zvivakwa uye kuwanda kwekushandisa. Inonyanya kushandisa nzira dzepanyama kana dzemakemikari kubatanidza uye kupindirana mafiibhi pamwe chete, kugadzira jira rine simba rakati uye kupfava. Kune akasiyana siyana ekugadzira matekinoroji emachira asiri akarukwa, uye akasiyana ekugadzira maitiro anopa asina-kurukwa machira akasiyana maitiro ekusangana akasiyana ekushandisa zvinodiwa.
Mumaindasitiri mazhinji akadai sehupenyu hwezuva nezuva, indasitiri, uye kuvaka, machira asina kurukwa anogona kuonekwa achitamba basa rawo:
1. Mundima yehutano hwehutano: masikisi, majasi ekuvhiya, zvipfeko zvekudzivirira, zvipfeko zvekurapa, sanitary napkins, nezvimwe.
2. Sefa zvinhu: mafirita emhepo, mafirita emvura, zvinoparadzanisa-mafuta-mvura, nezvimwe.
3. Geotechnical zvinhu: drainage network, anti-seepage membrane, geotextile, nezvimwewo.
4. Zvishongedzo zvezvipfeko: zvipfeko zvembatya, lining, mapepa emafudzi, nezvimwewo.
5. Zvinhu zvemumba: zvekurara, machira epatafura, maketeni, nezvimwe.
6. Mukati memotokari: zvigaro zvemotokari, sirin'i, makapeti, nezvimwe.
7. Vamwe: kurongedza zvinhu, bhatiri separators, zvemagetsi chigadzirwa insulation zvinhu, nezvimwe.
Maitiro makuru ekugadzira machira asina kuruka anosanganisira anotevera:
1. Meltblown method: Meltblown method inzira yekunyungudutsa thermoplastic fiber zvinhu, kuapfapfaidza kunze nekumhanya kukuru kuti aumbe mafilaments akanaka, uye oabatanidza pamwechete kuita machira asina kurukwa panguva yekutonhora.
-Kuyerera kwemaitiro: kudya kwepolymer → nyungudutsa extrusion → kuumbwa kwefiber → kutonhora kwefiber → kuumbwa kwewebhu → kusimbisa mujira.
-Zvinhu: Fine fibers, yakanaka kusefa kuita.
-Kushandisa: Inoshanda kusefa zvinhu, senge masiki uye zvekurapa kusefa zvinhu.
2. Nzira yeSpunbond: Nzira yeSpunbond ndiyo nzira yekunyungudutsa thermoplastic fiber zvinhu, kuumba fiber inopfuurira kuburikidza ne-high-speed kutambanudza, uyezve kutonhora nekuzvibatanidza mumhepo kuti iite jira risina kuruka.
-Kuyerera kwemaitiro: polymer extrusion → kutatamuka kuita filaments → kuisa mune mesh → kusungirira (kuzvisunga wega, kusungirirwa kwemafuta, kusungirirwa kwemakemikari, kana kusimbiswa kwemagetsi). Kana roller yakatenderedzwa ichishandiswa kumanikidza, nguva dzose inopisa yekutsikirira mapoinzi (pockmarks) inowanzoonekwa pane yakamanikidzwa jira pamusoro.
-Zvinhu: Yakanaka michina zvivakwa uye yakanakisa kufema.
- Zvishandiso: zvekurapa, zvipfeko zvinoraswa, zvinhu zvemumba, nezvimwe.
Pane misiyano yakakura muchimiro chemicrostructure pakati pemachira asiri akarukwa anogadzirwa ne spunbond (kuruboshwe) uye meltblown nzira pachiyero chimwe. Munzira ye spunbond, mafiibha nemagapu efayibha akakura pane anogadzirwa nemeltblown method. Ichi ndicho chikonzero nei machira asina kuruka akanyunguduka ane madiki madiki machira anosarudzirwa machira asina kuruka mukati memasiki.
